- Turning to the drawings, there is shown in
FIG. 1 a view of an exemplarywheel tractor scraper 10 having anelevator 12. Thewheel tractor scraper 10 comprises atractor portion 14 and abowl portion 16. Thetractor portion 14 comprises a cab oroperator station 15, an engine or other power source 17,tractor wheels 18, atractor frame 20 and a pair of rearwardly extendingarms 22 which pivotally support thebowl portion 16. - The
bowl portion 16 comprises abowl 21 havingsidewalls 26 and supported on arear frame 23, a pair ofwheels 24 and a moveable cutting plate (not shown) positioned between thesidewalls 26 underneath and near the forward end of thebowl portion 16. Theelevator 12 is mounted onto thebowl portion 16 between thesidewalls 26 and carries material from the cutting plate upwardly and rearwardly into thebowl portion 16. - As shown in
FIG. 2 , theelevator 12 comprises aframe 32 which attaches to thebowl sidewalls 26, amotor 34,sprockets 36 mounted at the upper end of theframe 32,guide wheels 38 mounted at the lower end of theelevator frame 32, a pair ofchains 40 and a plurality offlight assemblies 42. Thechains 40 are carried by thesprockets 36 and theguide wheels 38. Themotor 34 drives thesprockets 36 which in turn drive thechains 40. Theflight assemblies 42 are mounted at either end to thechains 40 in approximately evenly spaced relationship along thechains 40. Theelevator chains 40, and thus the flight assemblies 42, rotate counterclockwise or clockwise as indicated by the arrows. -
FIG. 3 is an exploded perspective view of aflight assembly 42 according to the present disclosure. Theflight assembly 42 comprises asupport member 44 and anedge plate 46. Theedge plate 46 serves as the digging component of theflight assembly 12 and is carried on thesupport member 44. Thesupport member 44 carries an attachment plate orbracket member 56 on either end for mounting theflight assembly 12 to theelevator chains 40. Theedge plate 46 may be welded or otherwise affixed to thesupport member 44. -
FIGS. 4-7 provide various views of an assembledflight assembly 42. The geometries of thesupport member 44 and theedge plate 46 are designed to provide adequate stiffness to theflight assembly 12. The materials of construction are selected to provide toughness while reducing the tendency of theedge plate 46 to brittle failure. - As shown in the figures, the
support member 44 comprises anelongated body portion 48 having an asymmetrical, U-shaped side profile with a substantially flat, elongatedtop section 51 and a substantially flat,elongated bottom section 53 connected along a curvedrear edge 52. As shown inFIG. 5 thetop section 51 has a length extending from oneend 50 to anopposing end 50 and a width extending rearward from afront edge 49 to therear edge 52. Therear edge 52 has a length and extends from oneend 50 to theopposing end 50. Thebottom section 53 has a length and extends from oneend 50 to theopposing end 50 and a width extending rearward from a forward edge 55 (FIG. 7 ) to therear edge 52. - Substantially L-shaped left and right
hand bracket members 54 are affixed to theopposing ends 50 of thesupport member 44 and are used to attach theflight assembly 42 to theelevator chains 40. Eachbracket member 54 has a substantially L-shaped profile when viewed from the front—see FIGS. 3 and 6—or rear—see FIG. 3—and comprises atop plate 56 and asidewall 58 joined to thetop plate 56 along anouter edge 60 and extending downwardly therefrom at substantially a right angle to thetop plate 56 to create the L-shape. Eachbracket member 54 has afront edge 63 and arear edge 64. Thetop plate 56 may be somewhat elongated and has a length extending from aninner edge 61 to theouter edge 60 and a width extending from thefront edge 63 to therear edge 64. In the illustrated embodiment, eachsidewall 58 has a somewhat irregular shape and has a height extending from theouter edge 60 downward to a substantially parallel butshorter bottom edge 65 and a width extending from thefront edge 63 to therear edge 64. Eachbracket member 54 may includeopenings 62 formed in thetop plate 56 to receive fasteners (not shown) for affixing theflight assembly 42 to thechains 40. - Each
bracket member 54 is affixed to and extends outwardly from anend 50 of thesupport member 44. Referring toFIG. 7 , a portion of therear edge 64 of eachbracket member 54 may abut the curvedrear edge 52 of thebody portion 48 and be affixed thereto by welding or other means. Thebracket members 54 may also be welded to theedge plate 46 to form a strong, unitary construction. In the assembledflight assembly 42, thefront edge 63 of eachbracket member 54 may extend forward (in front of) of the topsection front edge 49 and bottom sectionforward edge 55 of thesupport member 44 as shown inFIG. 7 . As best shown inFIG. 6 , each bracket memberinner edge 61 may extend inwardly from the respectivebracket member end 50. -
FIG. 8 is a rear view andFIG. 9 is a side view of anedge plate 46. Theedge plate 46 comprises anelongated body 70 having opposingends 72, atop edge 73 and a digging orcontact edge 74. Theedge plate 46 further comprises a front (forward facing)side 75 and arear side 77. As best shown inFIG. 9 , thebody 70 comprises an elongated, substantially planarupper portion 78 and an elongated, substantially planarlower portion 80 joined along a longitudinal bend orcrease 82 and defining an obtuse included angle when viewed from the side. As best shown inFIG. 8 , theupper portion 78, i.e., the portion of theedge plate 46 above thecrease 82, comprises a relativelywide section 88 and a coplanar but relativelynarrow section 86 extending upward from thewide section 88 away from thecrease 82. - The
narrow section 86 of theedge plate 42 is partially separated from thewide section 88 by a pair ofhorizontal slots 76 cut into or otherwise formed in theedge plate 46. As explained further below, theslots 76 are configured to receive thebracket members 54 when theflight assembly 42 is assembled. Thenarrow section 86 has first opposing ends 90, while thewide section 88 has second opposing ends 72. The width of thenarrow section 86 may be determined by, and preferably is about the same as, the width of thefront edge 49 of thesupport member 44. - The
edge plate 46 may be welded to thesupport member 44 or otherwise affixed thereto by any suitable means. For example, as best shown inFIG. 7 , when aflight 42 is assembled, therear side 77 of theedge plate 46 is positioned against thesupport member 44, with theupper portion 78 of theedge plate 46 abutting theforward edge 49 of thetop section 51 of thesupport member 44 and thelower portion 80 of theedge plate 46 abutting at least part of theforward edge 55 of thebottom section 53 of thesupport member 44. Thus theedge plate 46 may be welded or otherwise affixed to thesupport member 44 along two substantiallyparallel edges - In the assembled
flight assembly 12, thetop plate 56 of eachbracket member 54 extends through one of theslots 76 in theedge plate 44 and may contact theedge plate 44 along the surfaces around theslot 76. Theedge plate 46 may be affixed to thetop plate 56 along these areas of contact, thereby providing two more areas where theedge plate 46 can be secured to thesupport member 44. - The materials of construction of the
flight assembly 42 are selected to provide overall toughness while reducing the tendency of theedge plate 46 to brittle failure. Together as a combinedflight assembly 12, theedge plate 46 and thesupport member 44 provide improved wear resistance without reducing impact resistance. - Preferably the support member is made of a first material, and the
edge plate 46 is made of a second material that is harder and less flexible than the first material used to make thesupport member 44, because theedge plate 46 is subject to greater frictional forces, impact forces and other stresses than thesupport member 44. - More preferably, both the
edge plate 46 and thesupport member 44 are made of steel materials, with the edge plate steel material being harder and less flexible than the support plate steel material. - Still more preferably, the
edge plate 46 is made of hardened, heat treated steel and thesupport member 44 is made of rolled steel. - For example, the
edge plate 46 may be made of hardened, tempered quenched steel with a hardness of between about 360 BHN and 440 BHN and a compressive yield strength of between about 900 MPa (megapascals) and 1100 MPa. The support member may be made of a softer, rolled steel with a hardness of about 205 BHN and a compressive yield strength of about 500 MPa. - In another aspect of the invention, a method of making a work tool for an off-highway machine is provided. The method comprises the steps of: providing a carrying component made of a first steel material; providing a working component having a digging or cutting surface or edge and made of a second steel material that is harder and less flexible than the first steel material; and affixing the working component to the carrying component. The first steel material may be rolled steel. The second steel material may be a hardened, heat treated steel.
- The off-highway machine may be a wheel tractor scraper or other machine. The work tool may be a flight assembly for an elevator or other work tool. The working component may be an edge plate of the kind described above. The carrying component may be a support member of the kind described above.
- The flight assembly of the present disclosure finds general applicability with any elevator flight system for wheel tractor scrapers and other machines. The flight assembly improves the flight durability by using a harder material of construction in the leading edge plate and a less hard and more flexible material for the support member or back plate. The flight assembly improves wear resistance without reducing impact resistance.
- It is understood that the embodiments of the disclosure described above are only particular examples which serve to illustrate the principles of the disclosure. Modifications and alternative embodiments of the disclosure are contemplated which do not depart from the scope of the disclosure as defined by the foregoing teachings and appended claims. It is intended that the claims cover all such modifications and alternative embodiments that fall within their scope.
